WARNING:
You can be injured and the vehicle could be
damaged if you try to do service work on a vehicle
without knowing enough about it.
- Be sure you have sufficient knowledge, experience, the proper replacement parts, and tools before attempting any vehicle maintenance task.
- Be sure to use the proper nuts, bolts, and other fasteners. English and metric fasteners can be easily confused. If the wrong fasteners are used, parts can later break or fall off.
You could be hurt.
If doing some of your own service work, use the proper service manual. It tells you much more about how to service the vehicle than this manual can. To order the proper service manual, see Service Publications Ordering Information.
This vehicle has an airbag system. Before attempting to do your own service work, see Servicing Your Airbag-Equipped Vehicle.
Keep a record with all parts receipts and list the mileage and the date of any service work performed.
See Maintenance Record.
